Experts say that the simple act of sleep can pull water from your body, leaving you dehydrated. Citric acid—what's in lemon juice—helps the body's enzymes function, which in turn can stimulate your liver and help it detox. And the clean water helps return hydration to your body, while flushing out your kidneys. People who drink lemon water in the morning report that they experience a big mental boost and have increased energy!

Plus, it's filled with vitamin C—one lemon has 187 percent the amount you need in a day—which is a great antioxidant that helps boost your immune system.

To unleash these benefits, add the juice from half a freshly squeezed lemon to a glass of warm water (warm is apparently easier for your body to process than cold).

What do you think? Have you tried warm lemon water in the morning? Will you now?
